If you use some of the Lutron "Maestro" dimmers than you are limited to 10 locations, ie 8- 4 way switches.
Edited--- actually one master dimmer and 9 slave units.

"One" has ....and "one" was completely shot down and left in the corner in a puddle of their own bodily fluids ....that "one" was yours truly...and it was a brutal beat downlowryder88h said:
I don't have a link to that thread ...was before the forum software was "improved". The title of the thread was:
"Are 3-ways a neccessisty or a requirement"
...or something to that effect.
If someone could dig up that thread, I could relive that beating I took
EDIT:
I think I *may* have found it...
Are 3-way switches code or just convenience?
Come see the clown(me) stick his feet in his mouth!
LOL
Here is an excerpt/review of the festivities:

Celtic,
I thank you now, I just finished reading the past thread on this same subject, I'm now feeling violated but its agood thing that we have broad sholders. Again the NEC leaves you high and dry, it doesn't make sense not to us 3ways or 4 ways but the language is sort of ambiguous. With the cost of todays dwellings common sense says use them, wouldn't like to walk back down a set of stairs or turn around and walk to the other end of the hall to control that hallway light. Oh!!!! well that's why they make walkers.

That use to be a requirement around here but they did away with it. The idea was if the circuit went out (your lights) you wouldn't ignore it so the smokes would get energized immediately.

In all the years I have been putting in arc faults I have had only one trip and that was my man's fault (notice I didn't take the blame). Never had one tripped by a SD or anything other than the error in installation. I'll count my blessings

I also have never had a call back for a AFCI, so not sure what all the fuss is about them...

This is a typical trade school homework question.
You could.....but then the hallway circuit MUST be AFCI protected as well. Isn't there a SD in the bedroom?gtm87 said:
That falls into 210.12(B) language.
Nothing says you can't put the smokes, lights in hallway, and Bdrm outlets ALL on the same circuit with AFCI protection.

It's a local issue in different areas

In Connecticut they have ammended the code to remove smokes from the AFCI Circuit. They must be put on another circuit.

No, all they are saying is that it is not REQUIRED to be on a AFCI, but if you choose to you can...
(Amd) 210.12 Arc-fault circuit-interrupter protection.
Exception 2: Smoke detectors shall be permitted to be supplied by branch circuits without such protection providing such branch circuits supply no other outlets within the dwelling unit bedroom.
